I like the surrender option personally, I mean I keep usually keep fighting till the end, since any damage you do, any minion you kill gets you more Character Rank xp and Commander xp.
But I can also see when for example in Meltdown, a score of 300 to 50, a surrender to just end the match so you can get into another rather quickly is preferable to sitting there for another 3-5 minutes or so trying to fight back, when there is really no chance for a ‘come from behind’ victory.
Now Incursion, I think there is always a chance for a come back, in fact I was looking in the challenges and there is award for coming back to win Incursion when your last sentry is at 25% or lower health.
